The 9 Best PEO Companies in Massachusetts

If you’re looking to grow your business in Massachusetts, you’re in luck—there are plenty of cost-efficient and creative ways to boost your bottom line while saving time and money. However, some methods are more sustainable than others. Thankfully, working with a Professional Employer Organization, also known as a PEO, is without question one of the most effective. PEOs have plenty of expertise when it comes to providing quality HR services, such as staff training, payroll processing, and much more. 

We all want to save time, money, and internal resources. Just imagine how much more smoothly and profitably your business could run with a top-class PEO that is aligned with your business goals and objectives. Let’s take a look at the top three PEOs currently serving the Massachusetts market, all of which are more than capable of helping you with all your business needs. 

1. Coadvantage PEO Review

In Massachusetts, the standard of excellence is consistently sky-high—and that’s just one reason why Coadvantage never fails to go the extra mile for its extensive clientele. This PEO company, currently under the prestigious Morgan Stanley umbrella, has been gaining experience and expertise for decades and currently operates across all 50 states. 

So, what separates Coadvantage from its competitors? In Massachusetts, the business world benefits from a highly effective and enviable talent pool. Indeed, it’s a state in which one can find the most educated workforce in the whole country. While this is undoubtedly a good thing, it does mean that separating the very best from the rest (both within and outside of your business) can be a tough challenge. Coadvantage PEO provides the tools to achieve this with ease, and they’re hugely experienced in team-building for those in need of such services. 

For this reason, and many more, I’d highly recommend asking for a quote from Coadvantage and taking a closer look at its impressive offerings. 

2. Vensure HR PEO Review

If you’re looking for a PEO company to try for a short run, or if you’re brand new to the world of PEOs, then Vensure HR is a great option to go for. They’re up for working with businesses of all types and sizes, so there is nothing to worry about when it comes to minimum requirements or astronomic price ranges for smaller companies in Massachusetts. 

All concerns about efficacy and results can be put to bed when it comes to Vensure HR, as all standard services are covered, and, from our research, it’s clear that their operations are up to par with the needs of the contemporary business market. 

It’s worth bearing in mind, however, that while Vensure HR is a wide-ranging PEO that will happily work alongside almost any business, they’re generally regarded as being best suited to smaller operations. I’d advise getting a quote from them, yet as your business grows, it may be worth looking elsewhere for PEO services. 

3. Amplify PEO Review

There are plenty of PEO companies in Massachusetts, and yet Amplify PEO is the third and final company that I feel stands out from the crowd. Amplify PEO will work with the vast majority of business types, and they’re definitely worth a look if you’re seeking this kind of service. 

As most Massachusetts business owners would agree, Amplify PEO more than deserves its place on this list, if for their customer service credentials alone. As opposed to talking with a robotic voice, you’ll always be put through to a knowledgeable (and human!) member of staff, and will benefit from customized human solutions to the problems your business will face as it grows. 

For those with specialized business needs, it may be worthwhile looking elsewhere for your PEO solutions in Massachusetts. However, if you’re after a standard suite of payroll, benefits admin, team-building, etc., then Amplify has you covered. Get a quote, and see for yourself how good a fit they really are. 

4. Justworks PEO Review

Justworks is an increasingly popular contender on the Massachusetts PEO scene, launching in 2012 and expanding to cover the entire country. Just like every good PEO provider, Justworks covers all the essentials, including payroll, compliance, insurance, and perks, and they also provide a great level of transparency that makes them a solid option for Massachusetts businesses. 

If you go to Justworks’ website, you’ll be able to see their entire pricing structure. This might not sound like a big deal, but in an industry that is typically fairly opaque when it comes to costs, this makes a serious difference! In fact, the only reason why Justworks hasn’t made the top three on this list is that they simply haven’t been around for long enough to really establish their presence and their credentials. I’ve no doubt that in a few years, this firm will have the clout and the reputation to take on the biggest names in the industry, and in the meantime, they’re well worth looking into for your Massachusetts company’s needs. 

5. Infiniti HR PEO Review

In an industry awash with different firms, Infiniti HR manages to stand out from the crowd when it comes to serving Massachusetts businesses. As well as providing the full array of PEO services and HR support, this firm goes even further by providing recruitment services that really tick all the right boxes. Massachusetts has a broad talent pool, and as such, finding a PEO that excels in this area is like striking gold!

The only real downside to Infiniti HR is, once again, due to the fact they simply haven’t been around for that long. This PEO firm has only been operating in Massachusetts for 10 years, and as such, they lack the track record needed to make them a top choice in the state. 

6. TriNet PEO Review

TriNet benefits from being one of the most well-established PEO service providers in Massachusetts, with over 30 years of experience under their belt. While they will provide all of the essential services a Massachusetts business needs, they do tend to rest on their laurels when it comes to drawing customers, relying on their established reputation a little too much for my liking. 

There’s a real lack of innovation in this firm, and they aren’t considered anything special when it comes to customer services, either. So while they’re surely a perfectly functional PEO, they’re not going to make it to the top of this list any time soon unless some major changes take place. 

7. Oasis PEO Review

With 20 years of experience, Oasis is another well-established PEO serving Massachusetts businesses. They were recently acquired by PayChex, although they have managed to retain their own name for the PEO services. 

Make no mistake, Oasis will cover the essential array of HR services, and they have a strong reputation in a number of different fields and industries. However, I can’t help but notice that they have a minimum 12-month contract policy that seems out of step with contemporary business norms. In a world where month-to-month contracts have become part of the landscape, this just seems unnecessary and potentially off-putting to a lot of dynamic businesses in Massachusetts. 

8. ADP Totalsource PEO Review

ADP Totalsource is a serious international player when it comes to a PEO and currently offers HR assistance right across the globe. They provide all the essential services, industry-specific solutions, and have built up a powerful reputation on the scene. 

The downside? ADP is only really suitable for bigger, well-established companies and businesses. If you’re a small-to-medium operation in Massachusetts, the chances are you won’t get the customer care and attention you deserve or need, and as such, they aren’t as highly recommended as others on this list.

9. Insperity PEO Review

I won't sugarcoat it—I felt really let down by Insperity. They make no shortage of bold claims in their PR material, ranging from their impressive 30-year track record, a flurry of awards, and a wide-ranging array of products and services. Their cancellation policy, which allows for cancellation at any time with a 30-day notice period, also made them seem like a winning PEO for businesses in Massachusetts. So what went wrong?

It all comes down to healthcare. For whatever reason, Insperity only offers healthcare plans from a single provider, and as such, your employees’ healthcare options will be seriously limited with this PEO. If your employees aren’t getting the best healthcare plans for their needs, then there’s little point in going with a PEO! 

In-Depth Overview of Massachusetts PEO Services

Your business in Massachusetts can and will benefit from PEOs in a whole number of different ways. However, certain features should definitely stand out. Quality PEO service providers should be able to seamlessly manage any and all HR needs for your staff and should always be able to cover payroll management, cash flow management, tax filings, benefits administration, risk mitigation, and issues surrounding compliance too. 

A good PEO should also be able to assist with your recruitment needs, as well as employee training, expense reporting, and a host of other services as and when they are required. They can also help with finding better workers’ compensation rates, health insurance premiums, and more, as a PEO will be able to bargain with larger employee pools across the state. 

How to Evaluate a Massachusetts PEO Service Provider

As with every aspect of business in Massachusetts, there’s plenty to unpack when it comes to PEO service providers. However, I’ve looked into every aspect of the process in order to ensure you get a clear view of what you should be looking for. That’s why I’ve considered the following services and features when reviewing every PEO I investigate:
